DISPEN'SING--TAN K FOR LIQUIDS.

Specification of Letters Patent.

Patented Feb. 13, 1912.

To all whom may concern Be it known that I, OTTO A. HECKEL, a citizen of the United States, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in Dispensing-Tanks for Liquids, of which the following is a specification.

My invention relates to an improved dispensing tank for liquids and has for its object to provide a primary receptacle, one or more secondary receptacles which are charged with contents from the primary receptacle, means for connecting and disconnecting the interiors of said receptacles; means for indicating the quantity vof liquid contained in either receptacle, and means for preventing the entrance of foreign matter to the interior of either receptacle; and independent venting means for each receptacle.

In the drawings-Figure 1 is a perspective view of a device embodyingmy invention, showing a portion of the front wall broken away. Fig. 2 is a transverse sectional view of the inlet opening whereby the primary receptacle is charged, and its closure. Fig. 3 is an enlarged sectional View of the faucet employed in my invention, illustrating its mode of attachment to the receptacles, the faucet being open. Fig. 4 is an enlarged perspective view of the key of said faucet. Fig. 5 is another sectional view of the faucet, indicating the faucet closed and the key in position to recharge the secondary receptacle from the primary receptacle. Fig. G is a transverse sectional view of the faucet, showing the slot and groove which render its operation duplex.

As shown in the drawings, I employ a primary receptacle 7 whose top 8 is provided with an opening 9 surrounded by the collar 10, which collar 10 is screw-threaded to receive the screw-cap 11. The screw-cap 11 is provided with a depending connecting rod 12 provided with a vcounterbalancing weight 13 which is of a size sufficiently large to prevent its being withdrawn through the opening 9. The primary receptacle 7 is charged with liquid contents through the opening 9 and when so charged the counterbalancing weight 13 will draw the plug 11 to its seat to prevent the receptacle being accidentally left open, so that foreign substances might enter and clog or otherwise obsiltiruct the operation of the dispensing tan The primary receptacle is provided with a vertical gage 141 which is of glass or like material, and which registers with a scale 15. The gage is connected with the bottom of the receptacle 7 by means of the pipe connection 15 and at its top by a bracket, the upper end of the gage being provided with the opening 16 so that the gage 11 also serves as a vent for the interior of the receptacle 7 when it is rendered air-tight by the screw-plug being screwed into its seat within the collar 10. The air is admitted to the tank when the contents are drawn from the same through the faucet by passing downwardly through the gage and permitted to percolate upwardly through the contents from the bottom.

In the form illustrated in the drawings I have provided secondary receptacles 17-17, mounted immediately below the primary receptacles 7. y The bottom 1S of the secondary receptacle 17 is contoured in order to permit the duplex faucet 19 to be so mounted as to secure perfect drainage of the liquid contents. The faucet 19 is provided with a key 20. A slot 21 extends through the key 20, which is also provided with a groove 22 on one of its sides.

The main channel of the faucet 19 is indicated by the numeral 23. The supply pipe 24 enters the shoulder 25 of the faucet 19 at a point above the channel 23, the upper end of the tube 24 extending into the primary receptacle 7 (see Figs. 3 and 5). When the lever 26 of the faucet 19 is in the position illustrated by Fig. 3, the slot 21 will be in alinement with the channel 23 and the contents of the secondary receptacle will be discharged. I/Vhen the lever 26 is thrown to close the faucet by revolving the slot 21 out of alinement with the channel 23, the groove 22 will serve as a communicating channel between the mouth of the pipe 241 and the inner end of the channel 23, forming a conduit between the interior of the primary receptacle 7 and the interior of the secondary receptacle 17 (see Fig. 5). -When in the latter position it is obvious that the interior of the secondary receptacle 17 will be filled to its full capacity from the primary receptacle 7.

To admit the liquid to the secondary receptacle 17, a vent for said secondary receptacle 17 is necessary, which I have provided in the form of a tube 27 extending from the interior of the secondary receptacle 17 to a point above the level of the top of the primary receptacle 7; which is illustrated in the drawings by the projecting end 28 passing through the top 8, with which the primary receptacle 7 is provided.

The primary purpose of the device of my invention is to enable inflammable liquids, such as the hydro-carbon oils, to be accurately measured and dispensed in dark locations without the aid of a light. The secondary receptacles 17 are to be of such capacity, in fractions of a gallon, as will represent the quantities usually dispensed at retail or wholesale, by the dealer. Thus, in retailing kerosene at a retail price of 15e. per gallon, and to a trade demanding it in quantities of 5e. worth, 10c. worth, or 15e. worth at a purchase, the dispensing tank may be provided with any number of the secondary receptacles 17 having the respective capacities of one-third, two-thirds, and one gallon. The form illustrated in the drawing may be assumed to represent two of the secondary receptacles 17 having respective capacities of one-half gallon and one gallon.

In order that the operator may ascertain at a glance if the receptacle 17 has been properly refilled by the operation of the duplex faucet 19 and to prevent the fluid from rising into the vent-pipe 27, I have provided a float valve 29 mounted in each of the secondary receptacles 17 and having a rod 30 extending vertically through the vent-pipe 27 and out of the top of said ventpipe 27 and terminating in a bolt 31.

From the foregoing description it will be apparent that the operation of the faucet 19, when in its closed position, is to charge the secondary receptacle 17 with fluid contents from the primary receptacle 7. The operation of opening the faucet will interrupt the connection between the interiors of the primary and secondary receptacles and permit the contents of the secondary receptacle to be discharged. Vhen said contents have been completely discharged the faucet is again closed and in closing reverses the connection between t-he secondary and primary receptacles so that the former is recharged with liquid contents.

Among the advantages of the device thus described are that the dealer using the dispensing tank can see at a glance how much his t-otal sales have amounted to in quantity; while both dealer and customer are insured of having precisely the measurement of the fluid which is desired. It also enables inflammable liquids to be dispensed in locations and under conditions of darkness where the various ordinances for fire prevention and the rules of the various boards of underwriters prohibit the use of artificial light.

Having thus fully described my invent-ion, what I claim as new and desire to have secured to me by the grant of Lettersl Patent, is:

1. An improved dispensing tank for liquids comprising a primary receptacle, a secondary receptacle, a faucet connected to the secondary receptacle, a pipe connected to the faucet and'to the primary receptacle, said faucet provided with a key having a vport whereby the liquid from t-he primary tank may be fed by way of the faucet to the secondary tank, said key arranged to close off the connection between the faucet and primary tank when the faucet is operated to extract the contents of the secondary receptacle by way of t-he faucet, a vent pipe extending through the primary receptacle from the top of the secondary receptacle to the top of the primary receptacle, a float valve operating in the vent pipe to prevent the liquid in the secondary receptacle from passing into the pipe and a gage connected at its bottom to the primary receptacle for admitting` air through the same into the primary receptacle when the contents are being extracted, substantially as specified.

2. A device of the class described com' prising a primary receptacle and a plurality of secondary receptacles located beneath the same, a faucet connected to each of the secondary receptacles, a pipe connected to the primary receptacle and to the faucet, said i faucet provided with 'a key having a port by which the liquid from the primary receptacle is directed to the secondary receptacle for filling the same with liquid from the primary receptacle, said key provided with a second port to permit the liquid from the secondary receptacle to pass out by way of the faucet and during which time the passage from the primary receptacle is y closed by the key, a vent pipe connected to each of the secondary receptacles and passed upwardly through the primary receptacle, a float valve operated in each of said pipes, a gage located on the outer face of the primary receptacle and connected to the same at its bottom whereby air is admitted kinto the receptacle at the bottom when the faucet is operated for filling the sec-ondary receptacle from the primary receptacle, substan- A tially as specified.

In testimony whereof, I have signed my name to this specification, in presence of two subscribing witnesses.
